ABSTRACT:
A fiber optic network includes a fiber optic transmission channel with a first path and a second path. A set of fault-tolerant remote stations are connected to the fiber optic transmission channel, each of the fault-tolerant remote stations is configured to send and receive fiber optic overhead channel data on both the first path and the second path. A fault-tolerant master station connected to the fiber optic transmission channel includes a switch network and a logic network. The logic network generates first switch command signals to force the switch network into a standard configuration which results in the transmitting and receiving of fiber optic overhead channel data on the fiber optic transmission channel during normal operating conditions. The logic network is configured to assess the fiber optic overhead channel data to identify a fault on the fiber optic transmission channel and produce, in response to the fault, second switch command signals to force the switch network to assume a selected fault configuration such that the switch network continues to transmit and receive fiber optic overhead channel data from the fiber optic transmission channel during the fault.
